This invention relates 1:0 new and useful impro"vcments in seals, andpartiuularly to car seals.

One object 01 the invention is 10 provide a device 013 this chmacterwhicb is simple in construction, formed of few parts, and which cai1 bemanufactured at a 10W cost.

Another object is t0 provide a ca1 seal which is efiective in itsoperation, and which cannot be easily opened, by an unai1t-b0rizedperson, without detection.

Other objects and. advantages W111 be appmrent from the followingdescription when taken in connection wit-h the accompanying drawing.

In the drawing:

Fig1ue 1 is a perspective view 01 a ca1 sea1 made in accordance with thepresent invention, and in lockec1 position.

Figure 2 is an enlarged longitudinal sec tional View through the engagedende 0f the sea1.

Figure 3 is an enlarged vertical transverse sectional view on the line33 0f Figure 2.

Figure 4 is a p1an view of the blank fro1n which the casing is formed.

Figure 5 is a sectional view similar to Figure 2, but showing the freeend of the sea1 band about t0 enter the casing.

Referring particularly 130v the accompanying drawings, 10 represents thecasing' of the seal, which is formed from a sing1e length o1: metal, asmore clear1y indicated in Figure 4, and having one end of the ribbon 11properly folded into one end thereof, as shown at 12, and having itsother end open for the reception of the other, or free end of saidribbon. V

It Will 100 noted that the ship 01 mec-a1, from which the casing isformed, is folded upon itse1f. ab the intermediate portion thereof, andsuch portion, as shown at 13, extended int0 the interior of t-he casing,to a point adjacent the closed end thereof. The said intermediateportion 13 is spaceo'l to provide the open mouth of the casing, int0which the free' enc1 0f the ribbon enters, while the bight 0f saidportion 13 is provided with a slot 14:, the ends of Which ente1 t-headjacent portions 0f the sidesof said portion. Into this slot isproperly fitted 0ne end 0f the elongated ring 15, said ring being sp1itintermediate the bther end thereof, aS shown at 16, and the side walls01E the split beveled, at- 17, t0 be engaged by the arroW-head 18, 0fthe free end 0f fhe ribbon 11. The said sides cf the intermediateportion 13, 0f the casing. am formed with the a1ined openings 19, whilethe said arrow-head 18 is provided with corresponding openings 20,arranged to register with the forma openings to permit ready entrance ofthe ends of the ring 15, whereby t0 efi"ectively retain said -21110wheadwithin the casing. It Will be noted that the sa'1d arrow-head is formedby folding the und portion of the 1ibbon 11, 130 provide a sufficientnurnber of t-hicknesses of the ribbon to properly fi11 the mouth, 01'open end, of the casing, and thereby prevent entrance of any t001 whichmight be used 1:0 force 0pen the sea1.

VVhen the free en, 01' arrowhead 18 is inserted in the open end 01 thecasing, and pushed thereinto, the pointed end 0f said head engages ehebeveled faces 01 the split portion of the ring 15, and forces the endsthereof outwardly to s1ide on the outer face 0f the said head, and aftersaid head has been moved inwardly to its full extent, said ring endswill snap into the openings 20, to hold the ribbon end against removalfrom the casing.

In diametrically opposite sides of the nasing there are formed theelongated recesses 21, into which the flexing portions o-f the ring 15am adapted t-0 enter, as the ends thereof am separated by the enteringpointed head 0f the ribbon.

What is claimed is:

1. A cm seal including a casing having 0ne end open and its other endprovided wit-h a plurality of folds, a ribbon having one end securedwithin said folds and having its other end provided wit-h a transverseopening and arranged t0 be inserted into the open end of the casing, anda yoke he1d within the folded end of the casing and having the outerends 0f its arms arranged t0 be spread apart by the apertured end of theribbo n and to subsequently snap into said open1ng.
